We know the area around the Tarim Basin where the world-famous Urumchi mummies and others were discovered might not always have been a desert, because some of the grave yards were surrounded with wooden stockades, and many of the discovered graves were covered with wood. (See book cover, below, showing one such location).
But, a climate that would have supported enough trees to supply the wood necessary to construct the graveyards would imply a climate that was not conducive to the formation of dessicated mummies. So, I am at a loss.
Unwrapping Brooklyn's Mummies
July 23, 2009
There is an interview of Edward Bleiberg, curator of Egyptian, Classical, and Ancient Middle Eastern Art, and Lisa Burno, Head Objects Conservator, at the website for Archaeology Magazine, about the recent CT scans of four full mummies from the Museum's collection, the results of which yielded some surprises.
dondelion and I spent a day at the Brooklyn Museum during our May visit to New York, after I managed to get past the turnstyle in the subway where we caught the number 2 train that eventually got us to our destination. It has a great collection of ancient Egyptian artifacts - I believe I read that it is the third largest collection in the United States. When we go back to New York again (which I'm sure we will), we'll spend more time there - now that I know the mystery of how to get past the subway turnstyle (hint: the Port Authority should prominently display signs advising left-handed people to swipe their fare card with the right hand!)

The world’s first mummies: arsenic poisoning victims in Chile in 5000 BC
I had no idea that most strains of cannabis today originated in China! Fascinating article - and more of those troublesome blue-eyed certainly Caucasian mummies (this one was most likely a shaman) showing up in the far northwest region of China. [Map - shows how close Turpan a/k/a Turfan is to Urumchi a/k/a Urumqi - see prior posts under Mummies of Urumchi: (1) (2)].

Researchers find oldest-ever stash of marijuana
1 day ago
OTTAWA — Researchers say they have located the world's oldest stash of marijuana, in a tomb in a remote part of China.
The cache of cannabis is about 2,700 years old and was clearly "cultivated for psychoactive purposes," rather than as fibre for clothing or as food, says a research paper in the Journal of Experimental Botany.
The 789 grams of dried cannabis was buried alongside a light-haired, blue-eyed Caucasian man, likely a shaman of the Gushi culture, near Turpan in northwestern China.
The extremely dry conditions and alkaline soil acted as preservatives, allowing a team of scientists to carefully analyze the stash, which still looked green though it had lost its distinctive odour.
"To our knowledge, these investigations provide the oldest documentation of cannabis as a pharmacologically active agent," says the newly published paper, whose lead author was American neurologist Dr. Ethan B. Russo.
Remnants of cannabis have been found in ancient Egypt and other sites, and the substance has been referred to by authors such as the Greek historian Herodotus. But the tomb stash is the oldest so far that could be thoroughly tested for its properties.
The 18 researchers, most of them based in China, subjected the cannabis to a battery of tests, including carbon dating and genetic analysis. Scientists also tried to germinate 100 of the seeds found in the cache, without success.
The marijuana was found to have a relatively high content of THC, the main active ingredient in cannabis, but the sample was too old to determine a precise percentage.
Researchers also could not determine whether the cannabis was smoked or ingested, as there were no pipes or other clues in the tomb of the shaman, who was about 45 years old.
The large cache was contained in a leather basket and in a wooden bowl, and was likely meant to be used by the shaman in the afterlife.
"This materially is unequivocally cannabis, and no material has previously had this degree of analysis possible," Russo said in an interview from Missoula, Mont.
"It was common practice in burials to provide materials needed for the afterlife. No hemp or seeds were provided for fabric or food. Rather, cannabis as medicine or for visionary purposes was supplied."
The tomb also contained bridles, archery equipment and a harp, confirming the man's high social standing.
Russo is a full-time consultant with GW Pharmaceuticals, which makes Sativex, a cannabis-based medicine approved in Canada for pain linked to multiple sclerosis and cancer.
The company operates a cannabis-testing laboratory at a secret location in southern England to monitor crop quality for producing Sativex, and allowed Russo use of the facility for tests on 11 grams of the tomb cannabis.
Researchers needed about 10 months to cut red tape barring the transfer of the cannabis to England from China, Russo said.
The inter-disciplinary study was published this week by the British-based botany journal, which uses independent reviewers to ensure the accuracy and objectivity of all submitted papers.
The substance has been found in two of the 500 Gushi tombs excavated so far in northwestern China, indicating that cannabis was either restricted for use by a few individuals or was administered as a medicine to others through shamans, Russo said.
"It certainly does indicate that cannabis has been used by man for a variety of purposes for thousands of years."
Russo, who had a neurology practice for 20 years, has previously published studies examining the history of cannabis.
"I hope we can avoid some of the political liabilities of the issue," he said, referring to his latest paper.
The region of China where the tomb is located, Xinjiang, is considered an original source of many cannabis strains worldwide.

Great story on one of my favorite subjects: the mummies of Urumchi in the Tarim Basin.
The Dead Tell a Tale China Doesn’t Care to Listen To
By EDWARD WONG
Published: November 18, 2008
URUMQI, China — An exhibit on the first floor of the museum here gives the government’s unambiguous take on the history of this border region: “Xinjiang has been an inalienable part of the territory of China,” says one prominent sign.
But walk upstairs to the second floor, and the ancient corpses on display seem to tell a different story.
One called the Loulan Beauty lies on her back with her shoulder-length hair matted down, her lips pursed in death, her high cheekbones and long nose the most obvious signs that she is not what one thinks of as Chinese.
The Loulan Beauty is one of more than 200 remarkably well-preserved mummies discovered in the western deserts here over the last few decades. The ancient bodies have become protagonists in a very contemporary political dispute over who should control the Xinjiang Uighur Autonomous Region.
The Chinese authorities here face an intermittent separatist movement of nationalist Uighurs, a Turkic-speaking Muslim people who number nine million in Xinjiang.
At the heart of the matter lie these questions: Who first settled this inhospitable part of western China? And for how long has the oil-rich region been part of the Chinese empire?
Uighur nationalists have gleaned evidence from the mummies, whose corpses span thousands of years, to support historical claims to the region. Foreign scholars say that at the very least, the Tarim mummies — named after the vast Tarim Basin where they were found — show that Xinjiang has always been a melting pot, a place where people from various corners of Eurasia founded societies and where cultures overlapped.
Contact between peoples was particularly frequent in the heyday of the Silk Road, when camel caravans transported goods that flowed from as far away as the Mediterranean. “It’s historically been a place where cultures have mixed together,” said Yidilisi Abuduresula, 58, a Uighur archaeologist in Xinjiang working on the mummies.
The Tarim mummies seem to indicate that the very first people to settle the area came from the west — down from the steppes of Central Asia and even farther afield — and not from the fertile plains and river valleys of the Chinese interior. The oldest, like the Loulan Beauty, date back 3,800 years.
Some Uighurs have latched on to the fact that the oldest mummies are most likely from the west as evidence that Xinjiang has belonged to the Uighurs throughout history. A modern, nationalistic pop song praising the Loulan Beauty has even become popular.
“The people found in Loulan were Uighur people, according to the materials,” said a Uighur tour guide in the city of Kashgar who spoke on condition of anonymity for fear of running afoul of the Chinese authorities. “The nationalities of Xinjiang are very complicated. There have been many since ancient times.”
Scholars generally agree that Uighurs did not migrate to what is now Xinjiang from Central Asia until the 10th century. But, uncomfortably for the Chinese authorities, evidence from the mummies also offers a far more nuanced history of settlement than the official Chinese version.
By that official account, Zhang Qian, a general of the Han dynasty, led a military expedition to Xinjiang in the second century B.C. His presence is often cited by the ethnic Han Chinese when making historical claims to the region.
The mummies show, though, that humans entered the region thousands of years earlier, and almost certainly from the west.
What is indisputable is that the Tarim mummies are among the greatest recent archaeological finds in China, perhaps the world.
Four are in glass display cases in the main museum here in Urumqi, the regional capital. Their skin is parched and blackened from the wear and tear of thousands of years, but their bodies are strikingly intact, preserved by the dry climate of the western desert.
Some foreign scholars say the Chinese government, eager to assert a narrative of longtime Chinese dominance of Xinjiang, is unwilling to face the fact that the mummies provide evidence of heterogeneity throughout the region’s history of human settlement.
As a result, they say, the government has been unwilling to give broad access to foreign scientists to conduct genetic tests on the mummies.
“In terms of advanced scientific research on the mummies, it’s just not happening,” said Victor H. Mair, a professor of Chinese language and literature at the University of Pennsylvania who has been at the forefront of foreign scholarship of the mummies.
Mr. Mair first spotted one of the mummies, a red-haired corpse called the Cherchen Man, in the back room of a museum in Urumqi while leading a tour of Americans there in 1988, the first year the mummies were put on display.
Since then, he says that he has been obsessed with pinpointing the origins of the mummies, intent on proving a theory dear to him: that the movement of peoples throughout history is far more common than previously thought.
Mr. Mair has assembled various groups of scholars to do research on the mummies. In 1993, the Chinese government tried to prevent Mr. Mair from leaving China with 52 tissue samples after having authorized him to go to Xinjiang and to collect them.
But a Chinese researcher managed to slip a half-dozen vials to Mr. Mair. From those samples, an Italian geneticist concluded in 1995 that at least two of the mummies had a European genetic marker.
The Chinese government in recent years has allowed genetic research on the mummies to be conducted only by Chinese scientists.
Jin Li, a well-known geneticist at Fudan University in Shanghai, tested the mummies in conjunction with a 2007 National Geographic documentary. He concluded that some of the oldest mummies had East Asian and even South Asian markers, though the documentary said further testing needed to be done.
Mr. Mair has disputed any suggestion that the mummies were from East Asia. He believes that East Asian migrants did not appear in the Tarim Basin until much later than the Loulan Beauty and her people.
The oldest mummies, he says, were probably Tocharians, herders who traveled eastward across the Central Asian steppes and whose language belonged to the Indo-European family. A second wave of migrants came from what is now Iran.
The theory that the earliest mummies came from the west of what is now modern China is supported by other scholars as well. A textile expert, Elizabeth Wayland Barber, in a book called “The Mummies of Urumchi,” wrote that the kind of cloth discovered in the oldest grave sites can be traced to the Caucasus.
Han Kangxin, a physical anthropologist, has also concluded that the earliest settlers were not Asians. He has studied the skulls of the mummies, and says that genetic tests can be unreliable.
“It’s very clear that these are of Europoid or Caucasoid origins,” Mr. Han, now retired, said in an interview in his apartment in Beijing.
Of the hundreds of mummies discovered, there are some that are East Asian, but they are not as ancient as the Loulan Beauty or the Cherchen Man.
The most prominent Chinese grave sites were discovered at a place called Astana, believed to be a former military outpost. The findings at the site span the Jin to the Han dynasties, from the third to the 10th centuries.
Further clouding the picture, a mummy from the Lop Nur area, the 2,000-year-old Yingpan Man, was unearthed with artifacts associated with an entirely different part of the globe. He was wearing a hemp death mask with gold foil and a red robe decorated with naked angelic figures and antelopes — all hallmarks of a Hellenistic civilization.
Despite the political issues, excavations of the grave sites are continuing. Mr. Abuduresula, the Uighur archaeologist, made a trip in late September to the desert site at Xiaohe, where 350 graves have been discovered. The bottom layer of graves dates back nearly 4,000 years. More recent graves point to a matriarchal herding society that worshiped cows, Mr. Abuduresula said.
Somewhere in those sands, he said, archaeologists have discovered a woman as striking as the Loulan Beauty. She is called the Xiaohe Princess, and even her eyelashes are intact.
